-Here you’ll see a handful of JSON-RPC calls that Hardhat/Ethers made under the hood for us when we called the .deploy() function. Two important ones to call out here are [eth_sendRawTransaction](/developers/docs/apis/json-rpc/#eth_sendrawtransaction), which is the request to actually write our smart contract onto the Goerli chain, and [eth_getTransactionByHash](/developers/docs/apis/json-rpc/#eth_gettransactionbyhash) which is a request to read information about our transaction given the hash (a typical pattern when sending transactions). To learn more about sending transactions, check out this tutorial on [sending transactions using Web3](/developers/tutorials/sending-transactions-using-web3-and-alchemy/).
